D. For cold piping and piping with roller hangers, hangers and supports shall be <br />installed outside the insulation. Wherever hangers and supports are installed <br />outside the insulation, pipe insulation protecting shields or pipe saddles shall be <br />provided. Where insulation is not of sufficient strength to support the weight of <br />the piping, a half section of rigid cellular foam or high density fiberglass <br />insulation shall be provided under each shield. <br />E. Where insulation saddles are used, void between piping saddles shall be stuffed <br />with plastic insulation. <br />F. Insulation materials shall be installed in a first-class manner with smooth and <br />even surfaces, with jackets drawn tight and smoothly cemented down at all <br />longitudinal and end laps. Scrap pieces of insulation shall not be used where a <br />full length section will fit. <br />G. All surface finishes to be extended to protect all surfaces, ends and raw edges of <br />insulation. Omit insulation from vibration isolating connections, but adjacent <br />insulation shall be neatly terminated and beveled. <br />H. Insulation at equipment shall be so installed that the insulation may be removed <br />and replaced without the need of special skills or tools. Insulation on strainers <br />shall be installed with removable covers to facilitate cleaning of strainer. <br />I. Terminate insulation around these neatly with 45 degree bevel using a plastic <br />insulation. Pipe insulation shall be installed continuously with all joints tightly <br />butted. All lap and butt joint strips shall be securely sealed. <br />J. Insulation on all cold surfaces where vapor barrier jackets are used shall be <br />applied with a continuous, unbroken vapor seal. Lap and butt joints and fittings <br />seam edges shall be sealed with vapor barrier mastic and/or seam tape as <br />recommended by the manufacturer. <br />K. Hangers, supports, anchors, etc., that are secured directly to cold surfaces must be <br />adequately insulated and vapor sealed to prevent condensation. <br />L. Fittings shall be protected with a PVC jacket, which is to be installed with <br />welding adhesive, in accordance with the jacket manufacturer's recommendations. <br />3.11 Pipe Insulation Thickness: <br />A. Insulate all straight run piping according to current Model Energy Code or Table <br />1, which follows this Section. Where new insulation adjoins existing, taper to <br />match different thicknesses and seal tapers with mastic and jacket with PVC or <br />glass cloth. <br />City of Lino Lakes <br />Lino Lakes Fire Station #1 <br />RSI Project # 15-12120-02 <br />Plumbing (Roofing Related) <br />22 14 26-13 <br />
